In the majority of cases, planning consent will already exist under permitted development provisions. Sometimes however, local restrictions may apply if, for example,. .
(Images left to right: Compressor, Drilling Rig) When the drilling team arrives, they will be in one or two crew vehicles, the drilling rig will arrive. .
(Image: Water coming from borehole) We require and use water during the drilling process (we do need you to have a good water supply for our use), we will almost always hit water whilst drilling at some point / depth. The volumes involved can be considerable, as. .

(Image: Sump filled with spoil) In addition to water, the drilling will produce a wet aggregate of broken rock and soil from the borehole – generally about 1.5 tonnes of aggregate per 100m of depth. Unless otherwise stated, disposal of this spoil is the responsibility of.
